Itamar Supporter Languages: English (English ) Hebrew (עברית ) Timezone: Asia/Jerusalem (GMT+02:00)	Hi. Is this the plugin (WP-Katex) that you are using? https://wordpress.org/plugins/wp-katex/ If I understand correctly the problem is on the English page which is a translation of the Hebrew page. Is this correct? I'm not sure where I can see the problem of the missing forward-slash (/) symbol. Could you please attach a screenshot and explain to me exactly where the problem is? Thanks, Itamar.

Itamar Supporter Languages: English (English ) Hebrew (עברית ) Timezone: Asia/Jerusalem (GMT+02:00)	Hi. It seems that this is a compatibility issue with the WP-KaTeX plugin. This plugin is not officially compatible with WPML. You can check the full list of our compatible plugins here. https://wpml.org/documentation/plugins-compatibility/ Not being on this list does not mean that it is not compatible; it just means we do not know yet if it is. As for now, we can see that there is an issue with the LaTex tags. Can you please elaborate on what is the LaTex tags? I think that you are using shortcodes to insert those tags so maybe the issue is with the shortcodes. Are you using shortcodes for this? The way to handle compatibility issues with new plugins is to replicate the issue on a clean WordPress installation. After replicating this issue on a clean installation, I'll be able to consult and escalated, if needed, the issue to our compatibility team. For this, I created a test website with a clean WordPress install. You can access it through this link: hidden link Through this link, you will be automatically logged in. (If nobody logs in the test site will be available for one week from today.) Could you please install the WP-KaTeX plugin and see if the issue is replicable on a clean WordPress installation? Please configures WPML as it is configured on your site. Please also make sure that you are installing the latest version of the plugin. When done, please let me know what the results and where I can see them are. Thanks, Itamar.

amielR	latex tags come at the beginning and the end of every math equation and it looks like that on the backend of every post: [latex display="true"]y=\frac{x}{2}+3, x=2-y^2[/latex] and it looks like the attached image on the frontend. i also did what you asked but i gor an error message trying to configure wpml as it is configured on my site joxi_screenshot_1563886330986.png joxi_screenshot_1563885193182.png

Itamar Supporter Languages: English (English ) Hebrew (עברית ) Timezone: Asia/Jerusalem (GMT+02:00)	Hi and thanks for trying my suggestions. The issue indeed seems to be the removal of the backward slash (\) in the Translation Editor. I have found a workaround for this. After you complete the translation in the Translation Editor, you need to manually edit the English translation and add the backward slash (\) before 'frac'. I've tried it here and it works. hidden link What you need to do is to switch the language on the editing screen of the Hebrew post to English. Then you need to press 'ערוך בכל זאת' and you will be able to edit the English translation and add the (\). Then update the page. Is this the only problem with 'latex' tags? I ask it because now I want to escalate this issue to our compatibility team. Regards, Itamar.

Itamar Supporter Languages: English (English ) Hebrew (עברית ) Timezone: Asia/Jerusalem (GMT+02:00)	Hi, Amiel. Our second tier supporter came back to me regarding this issue. It seems that the issue of the backslash that is being removed in the Translation Editor is known to us and is escalated to our developers. The issue will be addressed in future versions of WPML. I have no ETA for when it will be ready. Fortunately, our has a workaround for this issue. Here is what you need to do. When translating the posts that contain the [latex] shortcode with a backslash (\) add another backslash in the translation side in the Translation Editor. For example, like so: [latex display="true"]y=\\frac{x}{2}+3, x=2-y^2[/latex] This solves the problem on the front-end. Please note that if you update the post and then the translation, you would need to add a double backslash (\\) again. Can you please try this workaround and tell me if it works for you? Thanks, Itamar.
